Abstract:A lithiumSulfur (Li-S) battery is expected as a next-generation power storage system because of high specific capacity (1,672 mAh g-1) of a S-based positive, which is about 10 times higher than that of a conventional intercalation-based positive in lithium ion batteries. However, lithium polysulfides (Li2Sx (x = 3 — 8)) are formed during charge/discharge and dissolve into an electrolyte. In our previous research, we successfully kept Li2Sx in microporous activated carbon [1], where an electrolyte could not pen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
